Acne vulgaris, a common skin condition in adolescents and young adults, arises from multifactorial issues within the pilosebaceous unit. Hormonal changes trigger increased sebum and altered follicular epithelium, leading to microcomedo formation and inflammation.

Area of Science:

  • Dermatology
  • Pathophysiology
  • Microbiology

Background:

  • Acne vulgaris affects 70-80% of adolescents and young adults.
  • It is a complex disease originating in the pilosebaceous unit.

Purpose of the Study:

  • To describe the pathogenesis of acne vulgaris.
  • To elucidate the role of androgens and microbial factors.

Main Methods:

  • Review of existing literature on acne pathogenesis.
  • Analysis of the biological processes involved in lesion development.

Main Results:

  • Androgen influence during adolescence increases sebum production and sebaceous gland size.
  • Follicular epithelium changes lead to microcomedo formation.

  • Propionibacterium acnes colonization and inflammatory responses contribute to acne lesions.
  • Conclusions:

    • Acne vulgaris results from a combination of hormonal, follicular, and microbial factors.
    • Understanding these factors is crucial for developing effective treatments.
